RDS-40WE

Wide Energy Survey Meter

The RDS-40WE is a Digital Handheld Dose Rate
Meter designed for use by personnel who may
be exposed to gamma and/or X-ray radiation in
their work. RDS-40WE provides either sequen­tial or  xed dose rate alarming system (values
are programmable by the CSW con gura­tion software via IrDA link) and the possibility
to store dose rate events into the histogram
memory of the meter.

FEATURES

• Wide Energy range 16.3 keV...3 MeV

• measurement according to H*(10)

• dose measurement indication

• high battery life time (>1 year)

• compliant to IEC 60846*

• dose rate follow-up by audible signal with frequency
proportional to dose rate

• visual and audible alarm: user settable for dose and dose
rate over the whole measurement range

• histogram capability of up to 480 dose rate
values with user settable logging interval

• backlight display with six large digits

• display in either μSv/h or in mrem/h

• built-in self diagnostics

• enclosure class IP67

* see Radiological Characteristics

The use of the RDS-CSW software (Mirion prod­uct # 1233-246) is required for downloading the
data into a PC via IrDA port.

RDS-40WE is microprocessor controlled. The
user interface consists of one push button and
an easy-to-use menu structure that displays
information in the LCD of the meter. The six­digit display shows the dose rate and various
messages. Di erent alarm situations are indi­cated by a combination of audio-visual e ects
in the LCD and a buzzer (dose rate, dose , low
battery, defect, dose rate over ow).

Complies with IEC 60486 and ANSI N42.33 standards
